iSCSI Target vs NFS Share
 

Hi,

I'm learning about these two techs at the moment, I've used nfs shares before but only with a shallow understanding and because some manual told me to. Never used servers running iSCSI Targets with client Initiators before. But considering the various issues and security vulnerabilities with nfs, what are your thoughts on the relative merits? Can the two be compared effectively or are their use-cases too different? How do they compare in terms of security and reliability for instance?

Both NFS v4 and iSCSI support security. Both run on TCP. The use cases are different since NFS provides file access and iSCSI provides device access. NFS access can be shared, while an iSCSI client without some sort of clustering software has exclusive access to the target block device. Both are easy to set up on the client side and much more interesting to configure the server properly.
